If you're thirsty for an old-fashioned chocolate soda, this landmark shop can quench that craving with three varieties: soda water spiked with Hershey's syrup ($2.75, with free refills); the Rhett Butler made with soda water, Hershey's and chocolate malt crunch ice cream ($3.75); and the classic, made with vanilla ice cream ($3.75).

If you've never had an Italian soda, you're in for a treat. In a tall glass, the barista combines flavored syrups such as raspberry, lemon, lime, pomegranate, hazelnut, peanut butter, blueberry, then adds cream (you can have it without), and fizzes it all with soda water ($2.50).

Grown-ups can get a taste of the Wild West with the Sonoran Draft Root Beer Float with Jack Daniels. As it sounds, it's a frosty mug of draft root beer, a shot of Jack Daniels whiskey and a scoop of vanilla ice cream ($12, $7 without the whiskey).

Go traditional with either a root beer float, also known as a Black Cow, made with Barq's root beer and scoops of vanilla ice cream ($6), or a Boston Cooler, made with Fanta ginger ale and vanilla ice cream ($6).

At this Fairmont Scottsdale Princess resort's bar and restaurant, drink the eatery's namesake in the Bourbon Malt made with Jim Beam and salty caramel ($11), or hop to it with the Grasshopper milkshake made with chocolate liqueur and crème de menthe ($11).

Think of a boba drink as a kind of Asian float, and what's floating (or sinking to the bottom) are fat balls of black tapioca for a truly unique beverage in such flavors as avocado, taro, coconut and chai tea ($3.29 and $3.79).

You can't beat the old-time milkshakes at Joe's, made with premium vanilla ice cream, milk, whipped cream and a cherry. If you want malt added, it's free. Choose vanilla bean, dark chocolate, strawberry, as well as shakes made with local medjool dates and other seasonal flavors ($4.49).

Would you like shakes with that? Made with Häagen-Dazs ice cream, Smashburger's shakes come in vanilla, chocolate or strawberry ($3.99), or as premium malts and shakes in Oreo, Butterfinger and Nutter Butter ($4.29).

First, choose your favorite ice cream, such as lemon, raspberry, blueberry or pineapple, and then have them mix you a milkshake, topped with rich housemade whipped cream, not that stuff from a can ($6 and $7.50).

Trim a few of the calories with a milkshake made from Italian gelato in such varieties as chocolate, Death by Chocolate (studded with brownie pieces), vanilla and espresso-chocolate ($4.47, $4.97 and $5.47).

Don't take even one sip of this sandwich shop's milkshakes if you don't want to drink the whole thing and maybe blow your diet -- they're that rich and good. Hand-dipped with real ice cream and milk, they come in chocolate, vanilla, banana, strawberry, Oreo and pineapple ($2.75, $3.50 and $5.50).

Sure, you can have a spot of tea, but why not something different, such as the Coffee Ice Cream Nectar? Think of it as a coffee float, with iced coffee, vanilla ice cream and flavors of cinnamon and orange ($5.95).

Papa Ed's encourages you to go crazy and have your root beer float, made with A&W root beer, prepared not with ho-hum vanilla but some other choice from their menu of 16 premium flavors, maybe mint chip, black cherry vanilla or fudge brownie ($2.25).

It's not your ordinary shake. The Misto is a blend of Italian ice and cool, creamy frozen custard. Flavors rotate among 50 varieties, but you might catch one in lemonade, mango or cherry ($3.49 and $3.99).
